I'm trying to use the "RenderTemplate" function in a macro. I am using the following code.

Important Notes:
 - I am using v 4.5 w/ <UseLegacyXmlSchema>true</UseLegacyXmlSchema> in umbracoSettings.config
 - This installation of umbraco is on a subdirectory
 - 1078 is a page node and 1080 is a template node.
 - This code worked for me previously. So, it should either be a problem with the 4.5 upgrade or the fact that this is on a subdirectory.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:Stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
<xsl:stylesheet 
  version="1.0" 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
  xmlns:msxml="urn:schemas-microsoft-com:xslt"
  xmlns:umbraco.library="urn:umbraco.library"
  exclude-result-prefixes="msxml umbraco.library">


<xsl:output method="xml" omit-xml-declaration="yes"/>

<xsl:param name="currentPage"/>

<xsl:template match="/">
<xsl:value-of select="umbraco.library:RenderTemplate(1078, 1080)"/>
</xsl:template>
</xsl:stylesheet>

When i place this macro on a template, I get this error where the macro should be.

Does anybody know why this is happening?

Thank you so much!
